Main and the supporting use of domestic gas-fired water heater of flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model, in the course of work of family expenses gas heater, heat in the high-temperature waste flue gas of domestic gas-fired water heater discharge is at first carried out preheating to the cold water that is input in the domestic gas-fired water heater, so that improve the leaving water temperature of domestic gas-fired water heater rapidly, when improving the domestic gas-fired water heater thermal efficiency, not only reclaimed the waste heat of high-temperature waste flue gas, saved the consumption of combustion gas, and, the service life of also having improved domestic gas-fired water heater effectively.
The utility model is mainly by fin, a left side has been adopted in the both sides of the condensing heat exchanger that water pipe and elbow are formed, right clapboard, and a fin and a left side, on the right clapboard, lower end surface all with shell on, following inwall opposite position forms sealed attachment by fluid sealant, a left side, before the right clapboard, the outer face of the flange that extend the rear end also in this simultaneously respectively with preceding, the inwall opposite position of bonnet forms sealed attachment by fluid sealant and fixes, make like this condensing heat exchanger be in shell and before, in the bonnet in the airtight relatively environment, high-temperature waste flue gas is concentrated behind the flue gas mouth by advancing of protecgulum entered vertically and in the segmentation fin gap of arranging of condensing heat exchanger, the high-temperature waste flue gas waste heat can be fully utilized, also can improve the thermal efficiency of preheating water in the water pipe greatly, leaving water temperature with rapid raising domestic gas-fired water heater, and also reduced and effluxed the high-temperature waste flue gas temperature, fin of the present utility model adopts segment of double drainpipe fin structure, hot side compared with the structure of single fin water pipe coiling is long-pending bigger, water pipe is with dislocation arrangement mode at interval, thermal current can more effectively coil water pipe and flow, and has improved the efficient of heat exchange.Be equipped with heat insulating coat on the inwall of described protecgulum and shell, scatter and disappear in the time of can reducing heat energy by protecgulum and shell effectively, further improved the service efficiency of high-temperature waste flue gas heat energy.
In addition, high-temperature waste flue gas is after the heat exchange of process condensing heat exchanger, water recovery Cheng Shui in the high-temperature waste flue gas, sour gas such as CO2, the NOX in the useless flue gas, SO2 also are dissolved in the condensed water simultaneously, therefore, the utility model has also been set up the condensed water neutralizing tank, make the not directly discharging of the condensate drain outlet pipe place of condensed water on the described shell bottom surface of flowing through, and enter the condensed water neutralizing tank again, with in the weak base nertralizer that presets and after discharge again, the waste water of Pai Chuing just no longer pollutes the environment like this.
Flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model is not only simple in structure, volume is small and exquisite, low cost of manufacture, and, easy to install, and use cost is also low, can couple together with existing domestic gas-fired water heater at an easy rate, need not change the structure of original pot-type boiler.
The effective drift diameter of flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model and surpass the flue of domestic gas-fired water heater, the air-flow at domestic gas-fired water heater smoke exhaust pipe road junction and pressure do not change after testing, can not influence the operate as normal of domestic gas-fired water heater.
Flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model also has security, be embodied in: flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model is connected in the running water pipe inlet channel and works, be a kind of passive device, do not need external power; Domestic gas-fired water heater start, flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model be operation together then, and gas heater cuts out, and then stops automatically; Flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model does not influence the utility model of the original smoke discharging pipe of domestic gas-fired water heater and the security of smoke evacuation; Flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model is not that naked light sprays because of the thermal process that is subjected at smoke discharging pipe; the water pipe hydraulic pressure of circulation preheating is identical with the family expenses gas heater; the temperature of water outlet is only than high 20 degree of water inlet; the also cooling rapidly of back smoke discharging pipe if domestic gas-fired water heater is ceased fire; running water in the water pipe that the circulation preheating is used also no longer heats up, so flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model service life is greater than more than 8 years.
In order to confirm the actual effect of flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model, and flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model is connected and supporting use by pipeline with a 10L energy rate gas heater, sees Table one through concrete test result.
Measured data in table one laboratory
Annotate: energy saver is the analysis of flue thermal-arrest energy-saving device of domestic gas water heater his-and-hers watches one data of the present utility model:
Because the energy that once absorbed of the every rising of water temperature is impartial, so can reflect energy-conservation percent efficiency with the difference of the temperature lift-off value of water outlet under the equal flow.
During flow 400L/h, (63-24)/(59-24)-1=11.4%,
During flow 350L/h, (71-25)/(66-25)-1=12.2%,
During flow 300L/h, (79-25)/(72-25)-1=14.9%,
This shows used flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model after, when flow was 400L/h, energy-conservation percentage was 11.4%.When flow was 350L/h, energy-conservation percentage was 12.2%.During flow 300L/h, energy-conservation percentage is 14.9%.
Setting under the equal firepower condition of the domestic gas-fired water heater situation, water flow is more little, and the temperature of the high-temperature waste flue gas gas of discharge is just high more, and the waste heat that can absorb is also many more.When discharge arrives 300L/h, waste heat makes leaving water temperature improve 7 degree on year-on-year basis, and exhaust gas temperature almost is exactly a room temperature, only exceeds 5 degree than entry water temperature, be lower than the delivery port water temperature of flue thermal-arrest energy-saving device of domestic gas water heater of the present utility model, the thermal efficiency of this moment is to peak.
